I am finally getting going on setting up my Minibow as a low/med light planted tank. I was planning on retrofitting an AH supply 13 watt kit into the existing hood. I figured this would meet my lighting goals for low/med plants. However, I realized the 13 watt bulb is 8 inches long, while the hood is 16 inches long. I would center the bulb but would it give me good enough light coverage for the tank? I would use a reflector with the bulb but I am concerned the ends of the tank might appear dim.
Any thoughts on this?
